She grew up in a home struggling with financial survival and is the mother of a child who receives speech therapy, has a paraeducator at his side, and an individualized education plan (IEP) at his elementary school. Following high school Nichole attended Woodland Community College, then left to care for her ailing mother while holding down two jobs to make ends meet. After her mother’s death, Nichole became guardian for her younger sister. Nichole faced even more challenges as a young child when she was seriously burned in an accident and received treatment at the UC Davis Burn Center. Later, when she was 9 years old the Fire Fighters Burn Institute offered her a chance to attend its Kids Camp.

Now Nichole volunteers with the Fire Fighters Burn Institute in Sacramento. Nichole is honored to serve as a First 5 Yolo commissioner because she is passionate about helping low-income at risk children and families get the services they need to survive and thrive; with no judgment about why they need help.
